Pinewood has been home to the James Bond stage since 1976 with its construction having cost £1.3 million. It was used during the filming of The Spy Who Loved Me and was created when the script called for filming of two submarines inside an oil tanker.
It burned to the ground in June 1984 towards the end of filming of Ridley Scott's Legend, but was rebuilt and reopened in January 1985 as the Albert Broccoli 007 Stage, to honour the producer of many Bond movies.
Another fire occurred in July 2006 after production ended on the Bond film Casino Royale and the set was later demolished and rebuilt in under six months.
The roof covering the stage, which had been transformed into a replica Venice for the £39 million budget Casino Royale, caved in.
Pinewood, which started life in 1935, has a long association with the Bond films, starting with the first movie Dr No in 1962.
Other famous Bond scenes that were filmed around the studio include a car chase in Goldfinger's factory and Spectre island in From Russia With Love.
